    Persuasive health educational materials for colorectal cancer screening

    This paper describes an effort to design and evaluate persuasive educational materials for colorectal cancer (CRC) screening. Although CRC screening is highly effective, screening rates in the US remain low. Educational materials represent one strategy for educating patients about screening options and increasing openness to screening. We developed a one-page brochure, leveraging factual information from the Centers for Disease Control and Prevention (CDC) and national guidelines, and strategies for persuasion from the human factors and behavioral economics literatures. We evaluated the resulting brochure with adults over the age of 50. Findings suggest that the educational brochure increases knowledge of CRC and screening options, and increases openness to screening. Furthermore, no significant difference was found between the new one-page brochure and an existing multi-page Screen for Life brochure recommended by the CDC. We interpret these findings as indication that the more practical and potentially less intimidating one-page brochure is as effective as the existing multi-page Screen for Life brochure.

    Provider Perceptions of Colorectal Cancer Screening Clinical Decision Support at Three Benchmark Institutions
    (2009-11) Saleem, Jason J.; Militello, Laura G.; Arbuckle, Nicole; Flanagan, Mindy; Haggstrom, David A.; Linder, Jeffrey A.; Doebbeling, Bradley N.
    Implementation of computerized clinical decision support (CDS), and its integration into workflow has not reached its potential. To better understand the use of CDS for colorectal cancer (CRC) screening at benchmark institutions for health information technology (HIT), we conducted direct observation, including opportunistic interviews of primary care providers, as well as key informant interviews and focus groups, to document current challenges to CRC screening and follow-up at clinics affiliated with the Veterans Heath Administration, Regenstrief Institute, and Partners HealthCare System. Analysis revealed six common barriers across institutions from the primary care providers’ perspective: receiving and documenting “outside” exam results, inaccuracy of the CDS, compliance issues, poor usability, lack of coordination between primary care and gastroenterology, and the need to attend to more urgent patient issues. Strategies should be developed to enhance current HIT to address these challenges and better support primary care providers and staff.

    Redesign of a computerized clinical reminder for colorectal cancer screening: a human-computer interaction evaluation
    (2011-11) Saleem, Jason J.; Haggstrom, David A.; Militello, Laura G.; Flanagan, Mindy; Kiess, Chris L.; Arbuckle, Nicole; Doebbeling, Bradley N.
    Background Based on barriers to the use of computerized clinical decision support (CDS) learned in an earlier field study, we prototyped design enhancements to the Veterans Health Administration's (VHA's) colorectal cancer (CRC) screening clinical reminder to compare against the VHA's current CRC reminder. Methods In a controlled simulation experiment, 12 primary care providers (PCPs) used prototypes of the current and redesigned CRC screening reminder in a within-subject comparison. Quantitative measurements were based on a usability survey, workload assessment instrument, and workflow integration survey. We also collected qualitative data on both designs. Results Design enhancements to the VHA's existing CRC screening clinical reminder positively impacted aspects of usability and workflow integration but not workload. The qualitative analysis revealed broad support across participants for the design enhancements with specific suggestions for improving the reminder further. Conclusions This study demonstrates the value of a human-computer interaction evaluation in informing the redesign of information tools to foster uptake, integration into workflow, and use in clinical practice.
